I think your blogspot article is fine.

A problem you will face is that you are competing in a FIERCELY competitive niche. There are not many keywords with more strong competition and more professional and sophisticated competition than web hosting.

Did I get you right - that you are getting traffic but no sales?

People shop around...they'll look at a number of sites, including review sites before they buy.

To make sales in the web hosting niche you may need to target a longer keyword phrase with less competition. I know of one Super Affiliate ( Brian Johnson) who targets the phrase "Hosting coupon" so you may have some luck with a slightly off the wall keyword like "Hostgator coupon"

Good luck!!
